Even if Noah was very worried, he didn't forget that they were crossing what could have been a No Man's Land. When he saw Mariz float up, he was bracing for the impact. He just didn't count on getting dragged down all of a sudden. He had no idea how Allan pulled them; he just knew they hit the ground.

If the talks earlier didn't happen, Noah would have demanded Belphegor for explanations. However, he didn't want to be on friendly terms with the demon prince for now. He didn't even want to hear the old man's voice.
